Chronic Myelomonocytic Leukemia

Subsequent ROC curve analysis of this cohort identified a cut-off value for the MO1 subset of 97.55% [Area Under the Curve (AUC) =0.661, P=0.027], which aligns with the WHO criteria. Peripheral blood monocyte subset analysis, particularly MO1 subset analysis, can effectively assist in CMML diagnosis, but exclusion of inflammatory conditions is required.

The identification of patients with NF1 and their interittent follow-up are important for the early detection of potential complications, especially tumorigenesis. This review aimed to summarize NF1-associated tumors in pediatric patients and recently developed targeted therapies for treating these tumors.

Importantly, the addition of TET2 mutation status to CPSS-Mol also improved the CPSS-Mol score performance. Taken together, TET2MT status, especially multihit TET2MT, defines a specific CMML phenotype and should be considered in future prognostic scores.

Loss of PRR14L prolongs SAC-dependent mitotic arrest in response to microtubule depolymerization but, paradoxically, leads to catastrophic mitotic errors upon SAC abrogation by MPS1 inhibitors. A model derived from our findings provides a rationale for exploiting MPS1 inhibition as a potential vulnerability in cancers containing either PRR14L loss of function mutations or FGFR-TACC3 fusions.

The median overall survival (OS) was 15.1 months for patients with pDC clusters versus 30.1 months for those without pDC clusters (p = 0.021 log-rank test, Kaplan-Meier analysis). We propose using IRF8 immunohistochemistry in CMML bone marrow evaluation.

CMML in patients aged 50 years and younger is rare and presents with unique clinical and mutational features, suggesting a distinct pathogenesis.

For predicting OS, IWG molecular classification had a Harrell's C-index of 0.75, compared with WHO5 and ICC Harrell's C-indices of 0.74 and 0.73, respectively. Altogether, these results show that the IWG molecular taxonomy can be applied in routine practice, with several classes exhibiting distinct clinical features and outcomes.
